Right, every project other than pythoncore and w9xpopen depends on the
pythoncore project, but that's all.  Guido doesn't normally change any code
in any other subprojects, so he doesn't notice this viscerally.  If you want
to be completely safe at all times, do Build -> Batch Build.  One step and
easy.  It won't recompile more than needed, although if the Python DLL
changes, it will pee away a little time relinking things against the new
core .lib file.
